Unlocking the Secrets of Human Color Vision: The Oz Technology
Imagine being able to see a color that doesn’t exist in nature, a color so vivid and saturated that it’s like nothing you’ve ever experienced before. This is the reality of Oz, a revolutionary technology developed by scientists at the University of California, Berkeley. Oz uses microdoses of laser light to stimulate individual photoreceptor cells in the human eye, creating a brand-new color dubbed “olo” that is unlike anything we’ve ever seen before.
The Science Behind Oz
The human eye is capable of seeing in color thanks to three types of photoreceptor cells, known as cone cells, embedded in the retina. Each type of cone is sensitive to different wavelengths of light, with S cones detecting shorter, bluer wavelengths, M cones detecting medium, greenish wavelengths, and L cones detecting longer, reddish wavelengths. However, due to an evolutionary quirk, the light wavelengths that activate the M and L cones are almost entirely overlapping, making it difficult to stimulate only the M cone cells.
To overcome this limitation, the researchers used a technology developed by Austin Roorda, a professor of optometry and vision science at UC Berkeley, which uses tiny microdoses of laser light to target and activate individual photoreceptors. This technology, known as a “microscope for looking at the retina,” is already being used by ophthalmologists to study eye disease.
The Oz System
The Oz system is a complex software that translates images and colors into thousands of tiny laser pulses directed at the human retina. The system uses a map of the unique arrangement of the S, M, and L cone cells on an individual’s retina, which is obtained through collaboration with researchers at the University of Washington. With this map, the Oz system can be programmed to rapidly scan a laser beam over a small patch of the retina, delivering tiny pulses of energy when the beam reaches a cone that it wants to activate, and otherwise staying off.
The Experience of Seeing Olo
The experience of seeing olo has been described by participants as visually striking and deeply immersive. The color is so vivid and saturated that it’s like nothing we’ve ever experienced before. According to Austin Roorda, “It was like a profoundly saturated teal… the most saturated natural color was just pale by comparison.”
The Potential of Oz
The Oz technology has the potential to revolutionize our understanding of human color vision and could one day aid in treating vision disorders or simulating sight loss. The technology could also be used to answer basic questions about human sight and vision loss, giving us a way to study the human retina at a new scale that has never been possible in practice.
Conclusion
The Oz technology is a groundbreaking achievement that has the potential to unlock new secrets of human color vision. The experience of seeing olo is a testament to the power of human innovation and the potential for technology to push the boundaries of what we thought was possible. As we continue to explore the capabilities of Oz, we may uncover new insights into the fundamental nature of human color vision and unlock new possibilities for treating vision disorders and simulating sight loss.
